What are the different classifications of culture media?
These are classified into six types: (1) Basal media, (2) Enriched media, (3) Selective (4) Indicator media, (5) Transport media, and (6) Storage media.
What type of media is used to determine oxygen requirements of microbes?
Thioglycolate broth is a multipurpose, enrichment, differential medium used primarily to determine the oxygen requirements of microorganisms. Sodium thioglycolate in the medium consumes oxygen and permits the growth of obligate anaerobes.
What are culture media classify the types of culture media with examples and their uses?
List of culture media used in microbiology with their uses
| Media | Uses |
|---|---|
| · Glycerol Saline Transport Medium | Transport stool specimen for typhoid bacilli |
| · Heated Blood Agar/Chocolate Agar | Growth of fastidious organisms (E.g. Hemophilus influenzae, Neisseria gonorrhoeae and S. pneumoniae |
What are the 3 classification of oxygen requirement for microorganisms?
The organisms are obligate anaerobes. The organisms are facultative anaerobes. The organisms are aerotolerant. The organisms are obligate aerobes.
What are the 3 types of bacterial culture media?
Bacterial culture media can be classified in at least three ways; Based on consistency, based on nutritional component and based on its functional use. 1) Classification based on consistency: Culture media are liquid, semi-solid or solid and biphasic.
What are the three types of culture media according to physical state?
Different types of culture media are typically divided, based on the physical state of the media, into:
- Liquid culture media, commonly called “broth”
- Solid and semi-solid culture media, commonly called “agar”
Which of the following are the oxygen requirements of molds?
For their growth, three things are necessary – moisture, oxygen, and food (wood, paper, and other parts). Without the presence of any of the three necessities, the fungi cannot grow or develop. Thus, oxygen is compulsory in their requirements. This makes them obligate or strict aerobes.
What are the oxygen requirements of bacteria?
The oxygen level has to be just right for growth, not too much and not too little. These microaerophiles are bacteria that require a minimum level of oxygen for growth, about 1%–10%, well below the 21% found in the atmosphere.
On what basis are bacteria culture media classified?
Classification: Bacterial culture media can be classified in at least three ways; Based on consistency, based on nutritional component and based on its functional use. 1) Classification based on consistency: Culture media are liquid, semi-solid or solid and biphasic.
